Segmental atelectasis during asthmatic attacks as a consequence of bronchospasm and hypersecretion are very frequent in children. The collapse of a lung instead is a very rare occurrence. We report two patients with acute exacerbation of asthma, showing an in complete response to bronchodilatory therapy. The clinical findings and chest X-ray were suggestive for collapse of a lung. An urgent fiberoptic bronchoscopy revealed obstruction of a stem main bronchus caused by sticky mucopurulent secretions. The aspiration improved dramatically the respiratory distress and the radiological picture. In these cases we recommended to perform an immediate bronchial aspiration by means of a flexible instrument without waiting a further deterioration of respiratory function before taking this decision.
哮喘发作期间因支气管痉挛和分泌过多导致的节段性肺不张在儿童中非常常见。相反，肺萎陷则极为罕见。我们报告了两名哮喘急性加重患者，他们对支气管扩张剂治疗反应不完全。临床症状和胸部X光检查提示有肺萎陷。紧急纤维支气管镜检查显示主支气管因粘性脓性分泌物而阻塞。抽吸操作显著改善了呼吸窘迫和影像学表现。在这些病例中，我们建议在做出该决定前，不等呼吸功能进一步恶化，立即使用柔性器械进行支气管抽吸。
